When send the indication

[annapalu]

Hi all,

i try to log event in memory, and when connection is established read value from E2C and send to APP. if i send characteristics when event BLE_GAP_EVT_CONNECTED arrive the indication is not send ( maybe i must wait a that the service is discover??)

How can i resolve this problem?

Thanks, Anna

You can only send indications and notifications after the client have enabled them, this is done by writing to the CCCD of the characteristic you want to indicate/notify.

Hi Petter,

thanks for the answer. Yes, sure the data must be when indication is enable. But if enable it, disconnect the app (Nordic Master control Panel), and i reconnect the indication is enable, yet. So i don't need to enable it. But in this case the event send before is lost. How can i understand when the indication is enable? Is there an event or a function that after the connection allow to check if the indication is enable?

Thanks, Anna

So you have bonded. What example are you using? What SDK and SoftDevice version?

[annapalu]

Yes, i have. i use a BLE Developer studio to create a custom profile and plug in for the Nordic SDK11 to generate the code for it. The softdevice is s132 version 2.0.0

Ok. Maybe you can use the DM_EVT_SERVICE_CONTEXT_LOADED event you get in device_manager_evt_handler()? Do something like:

if( p_event->event_id == DM_EVT_SERVICE_CONTEXT_LOADED)
{
    start sending indications
}

I use a peer manager not the device manager.
